Evolution CER Essay

The study of physical anthropology literally means; the study of ma ) While yes, this is physical anthropology, there is much more, such as the study of physic l development, genetics, and behavioral ecology. Through paleontology we can conclude that change most definitely did happen Approximately sixty million years ago, the creature Eohippus existed. It was a primitive horse, that possessed a long head, a short mane, three Hoover toes on it’s hind legs and four Hoover toes on it’s front legs. It was an herbivore that lived in the northern he misshape. ( 9 Fast forward roughly thirteen million years, and Meerschaums emerges.

Strap gel, it slightly resembles, Eohippus. It was larger, but the limbs were startlingly similar. The most notable difference, though, is its hoof. As opposed to four rather close toes, the Mere chippies had a large center toe, and two toes on either side, though farther apart. Once moor e, we leap through time about twenty two million years, rather close to present day. Thro e million year ago Queues emerged, which is Latin for horse. They have now developed a sing alular hoof on which they walk, also called “on toenail” ( 10 Developmental biology, as previously stated, brings forth evidence of vestigial ND homologous Structures.

Vestigial Structures are Structures that once had use, but no longer do, like the arrestor pill muscle. This would have been used by our ancestors, as it was today. It makes the hair stand on end, and our ancestors, having more hair, would u SE it as a reflex to appear larger to enemies. (1 1) Homologous structures are structures that a re similar to one another, but can be used in a different way. In a human arm, there are phalanx gees, metacarpals, the ulna, the radius, and the hummers.
